1. A method comprising:

  • operating an implantable medical device (IMD) in a ventricular pacing protocol (VPP), wherein the VPP is a pacing protocol that tolerates a complete cardiac cycle devoid of ventricular activity while providing for ventricular pacing in the cycle immediately subsequent to the cardiac cycle devoid of ventricular activity;

    sensing for ventricular arrhythmias;

    determining if a correlation between ventricular pacing in the VPP and the sensed ventricular arrhythmia is present;

    discontinuing the operation of the IMD in the VPP if a correlation is determined to exist.
